The Government has been given the go-ahead to challenge a High Court ruling that the Prime Minister must seek MPs' approval to trigger the process of taking Britain out of the European Union.
Permission to appeal has been granted by a panel of three justices, the Supreme Court announced on Tuesday.
In a statement, the Supreme Court said that "the case can now proceed to a full hearing".
It is expected that the proceedings will last four days beginning on December 5.
The case will be heard by all 11 Supreme Court justices.
At the completion of legal submissions, the justices will reserve their decision to a date "probably in the New Year".
